<p>In recent years, breakthroughs have been made repeatedly in the exploration of Carboniferous volcanic rocks in the Junggar Basin, which has shown good exploration prospect of volcanic rock reservoirs. Due to the great changes in the rock types and textures of Carboniferous volcanic rocks in the Junggar Basin, and the restrictions the means of exploration and the quality of geophysical data, there are still many difficulties and problems in the identification and interpretation of Carboniferous volcanic rocks at present, which has great difficulties to the oilfield seismic exploration. How to improve the resolution and identification ability of Carboniferous volcanic rocks through existing geophysical methods and technologies has great theoretical and significance. As different volcanic rocks have the characteristics of magnetic difference, comprehensive identification and delimitation can be carried out by comprehensive geophysical technology combined with magnetic anomaly and seismic. Based on the measured remanence of the carapace and the measured cores of the Carboniferous and the volcanic rock outcrop, and with the full use of the core description, thin section identification, well logging and other data, the quantitative relationship model of remanence-GR was established for the first time, and the synchronous inversion of remanence parameters and seismic reflection was realize, and the three-dimensional data body of volcanic rock remanence was obtained, and the plane distribution of Carboniferous volcanic rock was predicted, the prediction coincidence rate reached 85%, the precision was improved by 22% compared with the traditional seismic inversion, and good application results were obtained.</p>
